So, I just got a set of 33's for my 93 F150, and when off road they rub when turning. Stock suspension, no lift whatsoever. I'm thinking of just trimming my fenders for now, that way I can still run larger tires than with non cut fenders when I lift it, or I'll eventually put new front fenders on it once it is lifted. Here's a couple pics of the truck. You can see in the slightly flexed photo that I wasn't even able to turn my tires.

 

I think I clicked on a photo of my old crown Vic f150 by accident lol
